CALCULATING-MAC HINE.

To all fw hom it may concern Be it known that I, CARL RAsMUssEN, en-

gineer,y 4subject of the King of Norway, re- :siding at Brunswick, Germany, have invented--certain new and useful Improvements in f Calculating-Machines, of which the following is a specification.

:2,k Myinvention relates to improvements in :carrying mechanisms such as. are used in l calculating machines and the like.

I `More'particularly my invention relates to @machines of this class inV which a setting mechanismand a registering mechanism are provided which.-are movablel relatively to 'each other.- Incalculating machines the setmechanism.

1 The object of the improvements is to pro- `vide accarrying mechanism for machines of thisclassiin rwhich all the operative parts nare-.movable with the registering mechanism.

.'IVith this yobject in view my invention 'consists `in the. matters to be described herey inafter and particularly pointed out in the appended claims.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing, in which the same letters of reference have been used in all the views to indicate corresponding parts.

In said drawing- Figure 1, is a vertical cross-section of the calculating machine, and

' Fig. 2, is a partial plan view of the saine with the cover of the casing partly removed.

For the purpose of explaining the invention reference will be made to a `calculating machine of the type shown and described for example in the patent of the United States No. 1,100,689 granted to me June 16, 1914. But I wish it to be understood that my invention is not limited to the construction shown in the drawing, nor to the use in combination with a calculating machine.

Referring to the drawing, the calculating machine consists of a setting mechanism which comprises setting disks a secured to a rotary shaft g and provided with radially shiftable teeth Z, and of a registering mechanism which comprises numeral wheels 7c and gear wheels 7a2 connectedone with each of the numeral wheels. The registering mechanism is mounted on a slide or carriage Specification of Letters Patent.

which is adapted to be shiftedalong the setting mechanism. The values set on the setting disks by shifting the proper number of teeth b into operative positions are 'transmitted to the numeral wheels throughintermediate gear wheels n which are mounted on the slide 7c3.

The numeral wheels 7c .or the gear wheels 702 are each provided with a nose 701 which is located in such a position that when the corresponding numeral wheel passes Jfrom its nine position to its zero position a rocker z. is rocked which is mounted on a shaft z'. flhe said rocker is made integral with an arm 71.1 which carries a block g 'having 'two cam faces directed to opposite sides. The said block is located at the side ofa disk f which is provided with a radially shiftable tooth c (or where the machine is constructed for operation in both directions with two teeth e one for multiplication and the other one for division). All the disks are rotated from the machine crank by a mechanism -which will be described hereinafter, and

when a disk is thus rotated inwhich .the tooth e has been shifted into operative position, the intermediate gear wheel coperating with the numeral wheel of the, next higher order is advanced the \distance which corresponds to one value, and this rotation is transmitted to the coperating .numeral wheel. The tooth e is provided with a nose e1 which projects laterally therefrom and into y position for engagement with the block g, so that it rides on the latter when the block has been set by the nose cl in operative position.

After the rocker 7L, 71,1 has been rocked by the toothA lvl into operative position, it is held in such position, until the carrying operation is completed. For this purpose the rocker is' provided with a shoulder h2 which is adapted to be engaged by a spring Z ,whenthe rocker has beenv locked. The

mit thesame to drop with the blocks g into inoperative positions. In the preferred form of the invention. shown in thedrawmg the shaft -m is automatically rocked a through mechanism connected With the machine 'crank andthe shaft g.' As shown a" Icam 'diskff is mounted on the shaft c, Which isadaptedto strike a lever-'m1 secured to the "s haftm sopas to rock rthe saine Awith the springsd :away from" the rockersv ia ithe disks-f, and vsuoli. rotation must be p formed' 'in any position. ofzthe'slide k3' I5 rel l thiisgf'a vshaft o' is mounted on 1the'stationary :fp artj'WE-0f the machine near the slidefksfand parallel tothe direction of the' movement olfv fthe slide indicated inI Fig; 2 by the arrow The shaft o is adapted to vbe rotated from the machine crank 'g through Ytheinterme diary of gear Wheels p, p1, and p2.' 'On the shaft o a gear Wheel r is mounted which l takes part in the rotation of the shaft and longitudinally shiftable thereon, and the said gear Wheel is connected with a gear Ymechanism andits numeral Wheels, and a Ystationary' v mechanism vvalues thereto, of carrying members movable with the registerin'gmechanism, means controlled by and movable With the numeral AS Statedbefore, the carrying'- operation 1 ludes :rotation of the' shaft ,c which car ati-vesto the stationary-casing.- f'loeleot Y described, the combination with. a movable registering.4
